Specification of Letters Patent.

Patented Nov. 13, 1906.

Application filed February 17, 1905. Serial No. 246,113.

NEY, residing at New York, in the county of New York and State of New York, and THOMAS J. MIToHELL, residing at Conn'ellsville, in the county of Fayette and State of Pennsylvania, citizens of the United States,

have invented a new and useful Coke-Drawing Machine, of which the following is a specification.

This invention relates to machines of that class employed for drawing coke from ovens, and has tor its principal object to provide an efficient and readily-handled machine by which the coke may be withdrawn from all parts of the oven.

A further object of the invention is to provide a device of this class in which the oscillating fulcrum of the scraper-handle or drawbar may be adjusted close to the door of the oven to permit the scraper to pass over all portions of the hearth of the oven without unduly increasing the width of the doorway.

A still further object of the invention is to provide a draw-bar having both tilting and oscillatory movement in which the two fulcrums are sufiiciently remote from each other to permit proper handling of the draw A still further object of the invention is to provide an improved tilting and controlling mechanism which will at all times be within convenient reach of the o erator.

A still further object o the invention is to provide mechanism by which the operator ma with one hand control both the vertical an swingin movement of the draw-bar.

A still lurt er object of the invention is to provide means whereby the entrance of the scraper-blade into the mass of coke may be facilitated without danger of injury to the blade.

With these and other objects in view, as will more fully hereinafter a pear, the invention consists in certain nove features of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions,'size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is an end elevation of a coke-drawing machine constructed in accordance with the invention, showing a coke oven in section. a Fig. 2 is a plan view of the same, the coke-oven being shown in section. Fig. 3 is a front elevation of the machine. Fig. l is a transverse sectional elevation of a portion of the same on the line 4 4 of Fig. 2, the view being on an enlarged scale. Fig. 5 is an elevation of portions of the structure shown in Fig. 4 looking in the direction of the arrow, the parts being in slightly-different position and the drawbar being shown in section. Fig. 6 is a detail sectional view of a portion of the machine, showing the controlling-lever for manipulating the motor-starting device. Fig. 7 is a detail View of one end of the draw-bar, showing the connection between the latter and the cable or chain. Fig. 8 is a detail sectional view. Fig. 9 is a detail perspective view of the inner end of the oscillatory sup porting-arm of the draw-bar.

' Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the draw- 111 s.

Tn modern practice rails are laid on the ground in front of a plurality of coke-ovens, and a wheeled frame, carrying suitable. drawing mechanism, is arranged on the rails and 'moved in front of the successive ovens in order to. withdraw the coke therefrom. The present machine belongs to this class of devices and is arranged to travel on suit-able rails 10. i

The frame includes in general the sill members 11, from which rise standards 12, that are connected at the top by cross-bars 13. Projecting from the upper portion of that side of the frame nearest the oven is a bracket 14,- carrying a verticall -disposed stud-bolt .15, on which is pivotecl the inner end of a swinging arm-16, which may be oscillated in a horizontal plane, the stud constituting what is hereinafter termed for convenience the oscillatory fulcrum 'of the draw-bar. The outer end of the arm is provided with a recess 17, Fig. 4, that fits-over the inner edge of a segmental barlS, that is rigidly secured to the frame, the curved lines of the bar being struck from the vertical center of the stud and the outer end of the arm being at all times supported by said segmental bar.

Near the outer end of the arm are pendent is hereinafter termed the tilting fulcrum of the draw-bar. To the inner end of the arm 16 is pivoted a-link 25, that is connected by a pin 26 to two links 27 and 28, these constituting a toggle-lever. From the lower link 27 extends a spindle 30, on which are hung two brackets 31 and 32, said spindle also carrying an antifriction-roller 33, that rides on top of the draw-bar, Fig. 5. The

, bracket 32 is approximately U-shaped in form and carries a spindle 34, on which is mounted an antifriction-roller 35, that carlies a portion of the weight of the draw-bar, the two rollers and the bracket constituting guides for said bar. The brackets.31 and 32 are provided with horizontally-disposed ears, through which extends an arbor or spindle 36, on which is mounted a double sheave 37. To the lower end of the bracket 32 is rigidly secured a stud 40, Fig. 8, on which is pivoted a block 41, and from the opposite sides of the block extend pins or bolts 42, on which are pivoted the inner ends of a pair of convergent bracing arms 43. The outer ends of the arms 43 are pivoted to a horizontally-die posed shaft 44, that is supported by suitable rackets 45, carried by the outer standards of the frame. The link 28, herein-before referred to, is connected at its outer end to the inner arm of a bell-crank lever 49, pivoted on a bracket 50, carried by the arm 16,-and the .outer end of said bell-crank lever forms an operating-handle, which when moved will tilt the drawbar, causing it to move up and down in a vertical plane with the upper spindle 21 as a fulcrum. This lever also serves as a means for swinging the draw-bar on its oscillatory fulcrum, so that the operator may with one hand move the draw-bar in all directions.

The frame is provided with bearings for the reception of a vertically-disposed shaft 52, on which is secured a winding-drum 53, and around said drum passes a flexible cable or chain 54, that is guided around the sheaves 37, one end of the cable being secured near the inner end of the draw-bar and the other. at or near the outer end thereof. By turn ing the winding-drum stress is exerted on the cable in one direction or the other and the draw-bar will be moved longitudinally either into or out of the oven.

On the shaft 52 is secured a bevel-gear 55, with which intermeshes a bevel-pinion 56, that is secured to a shaft 57, ada ted to suitable beari-ngs in the frame. e shaft 57 carries a gear-wheel 58, with which intermeshes a pinion 59 on the armature-shaft of a motor 60, an electric-motor being here shown for purposes of convenience, although any other suitable power may be employed. Associated with the motor is a controller 61, which may beof any ordinary ty e, the controller-shaft 62 being shown in 2 as extending out through one end of the controller-casing and carrying a sprocket-wheel 63, that is connected by a hnk belt 64 to a sprocket-wheel 65 on oneend of a controlling-rod 66.

' The controllin -rod 66 has circular end portions mounted in bearings 67, carried by the frame, while that portion of the rod between the two bearings is of rectangular or other non-circular form. On this rod is mounted a controlling-lever 68, having an opening corresponding in contour to the cross-sectional contour of the: rod, and the rod further carries a U-shaped frame 69, that is connected by a'link 70, the opposite end of which is pivoted to a standard or bracket 71, rising from the arm 16, the purpose of this connection being to maintain the controllinglever 68 at all times within a convenient distance from the tilting lever 49, so that one may be grasped in one hand and the other in the other hand of the operator. This mechanism, as will appear hereinafter,is impor tant in the operation of the draw-bar in that it permits readyreversal of the movement of said draw-bar during the operation of drawing out the coke and returning the scraper to position within the oven. It is furthermore .of importance in that it permits of the ready introduction of the scraper-blade into the mass of coke immediately in advance of the drawing operation. The coke is usually in large masses and it is a matter of some dilli culty to properly introduce a scraper there- 1nto.

' The frame is provided with bearings for the reception of a shaft 80, carrying sprocketwheels 81, over which pass link belts 82, forming parts of a traveling conveyer 83, arranged to deliver at any convenient point. The conveyer is operated by any suitable mechanism, a motor 84. being illustrated in the present instance. The frame is further provided with supports for an inclined and curved chute 85, preferably provided with vertical side flanges, and in operation one end of the chute is arranged opposite the door way of the coke-oven and the opposite end is is moved to a position'in'front of the oven.

from which the coke is to be drawnand the chute is turned around to the posit-ion shown in full lines in Fi 2. The operator then movesthe controlling-lever 68, and by turning the rod 66 in the proper direction the motor will be actuated to Wind the cable and move the draw-bar into the oven. Prior to this movement the lever 49 is pulled down in order to operate the to gle-levers and elevate the scraper-blade, so t at it Will swing clear over the top of the mass of coke. This being accomplished, the lever 49 is moved in the opposite direction to press the scraoer-blade' down into contact with the coke and by operating the controlling-lever 68 the motor may be reversed to eiiect a to-and-fromovement of the draw-bar while the blade is being pressed downward into the coke. As the scraper-blade is pressed downward it will advance in a zigzag path to an extent sufiicient to bury it wholly or artly in the mass of coke, securing suilicient liold to permit the Withdrawal of the coke from the oven. This 0 eration is repeated as often as necessary, t e tilting fulcrum permitting the blade to move up and down, while the oscillatory fulcrum permits adjustment of the draw-bar to bring the blade over the Whole of the area of the oven. By this means the whole of the contents of the oven may be withdrawn, the position of the oscillatory fulcrum close to the outer wall of the oven permittin the free swingin movement of the blade without on duly wi ening the doorway.
